AI Engineer (Agentic Systems Focus)

A highly technical role within a large, data-driven organization seeking an engineer to design and scale agentic AI systems and intelligent applications. This position focuses on building production-grade AI systems that enable autonomous decision-making, multi-step reasoning, and workflow automation across enterprise environments.


Core Responsibilities

Agentic AI & LLM Systems

  • Design and deploy agent-based systems capable of multi-step reasoning, tool usage, and autonomous execution
  • Build workflows using LangChain, LangGraph, LlamaIndex, or similar frameworks
  • Implement tool-calling architectures integrating APIs, databases, and enterprise systems
  • Develop multi-agent workflows, prompt strategies, and evaluation frameworks

RAG & Knowledge Systems

  • Build RAG pipelines using enterprise data (structured and unstructured)
  • Design embedding strategies, retrieval pipelines, and context optimization
  • Manage vector databases (Pinecone, Weaviate, pgvector, etc.)
  • Enable semantic search and enterprise AI copilots

AI Systems & Infrastructure

  • Architect systems supporting stateful agents, memory, and real-time decisioning
  • Integrate AI into business workflows and enterprise systems
  • Establish guardrails, observability, and reliability standards

LLMOps & Production

  • Deploy AI systems in cloud environments (AWS, Azure, GCP)
  • Build CI/CD pipelines for LLMs, agents, and data workflows
  • Implement monitoring, evaluation, and feedback loops

Applications & Interfaces

  • Build AI-powered tools, copilots, and assistant interfaces
  • Integrate backend AI systems into scalable user-facing applications

Required Experience

  • 8+ years in software, data, or ML engineering
  • Strong Python experience (production-level)
  • Hands-on experience with LLMs, RAG systems, and agentic workflows
  • Experience with LangChain, LangGraph, LlamaIndex, or similar tools
  • Familiarity with vector databases and embedding pipelines
  • Experience with cloud platforms (AWS, Azure, or GCP)
  • Strong background in API development and scalable systems
  • Experience with LLMOps / MLOps practices
